摘要：

Amine Alamine 304 dissolved in xylene reacts with hydrochloric acid to form the amine chloride (R3NH+Cl+) and the amine dichloride (R3NH2Cl2). The former compound was isolated and characterised by chemical analysis, X-ray powder diffraction, infrared spectroscopy and scanning electron microscopy. Lattice parameters of the isolated amine chloride were determined and refined by least-square numerical treatment (monoclinic cell, with a = 29.017 Angstrom, b = 14.564(7) Angstrom, c = 5.043 Angstrom, b = 95.68(3) degrees and V = 2,120 Angstrom(3)). The amine chloride is a potential anion-exchanger with metals, thus data on the liquid-liquid extraction of Co(II), Au(III) and Pt(IV) are also reported.
